Which methods are best used to achieve ALARA?

• A. Increase time and dose
• B. Implement a combination of these actions
• C. Defer all tasks
• D. Rely on luck

Answer: (B)

ALARA means keeping radiation exposure as low as reasonably achievable by using a mix of protective actions. The best approach is to implement a combination of actions—plan to minimize time spent in the radiation area, maximize distance from the source, and use shielding and appropriate controls. When these measures are combined, they work together to reduce dose much more effectively than any single measure on its own, which is the essence of ALARA. The other options fail because increasing time or dose does the opposite of protection, deferring all tasks stops work, and relying on luck is not a safe or acceptable strategy.
